Arrowhead

Abstract

A mechanical broadhead arrowhead having a plurality of delayed deployment blades pivotably connected to the body of the arrowhead. Each blade has a longer knife portion and a shorter wing portion. The wing portion has a sharpened edge along at least part of the side facing the knife portion. The blade has a pivot point where the centerlines of the knife portion and wing portion intersect.

I claim: 
     
       1. A mechanical broadhead arrowhead comprising:
 (a) an elongated body defining a longitudinal axis, the body having a forward end with a sharpened tip, a threaded rearward end for attachment to a shaft of an arrow, and a plurality of recessed slots parallel to the longitudinal axis; and 
 (b) a plurality of delayed deployment blades pivotably mounted in the slots, each blade having a longer knife portion with a centerline and a shorter wing portion with a centerline, the knife portion having a sharpened edge along the side opposed from the wing portion, the wing portion having a sharpened edge along at least part of the side facing the knife portion, each blade having a pivot point where the centerline of the knife portion intersects the centerline of the wing portion, the centerline of the knife portion and the centerline of the wing portion forming an angle of about 45 to 75 degrees, each blade adapted to rest in a first position with its knife portion in a slot of the body and with its wing portion extending outwardly with its sharpened edge facing forward and being forward of the pivot point during flight, and each blade adapted to move to a second position with its wing portion in a slot of the body and its knife portion extending outwardly with its sharpened edge facing forward after deployment upon contact with a solid target. 
 
     
     
       2. The arrowhead of  claim 1  wherein the body is generally cylindrical. 
     
     
       3. The arrowhead of  claim 1  wherein the number of recessed slots is two to four. 
     
     
       4. The arrowhead of  claim 1  wherein the body contains a plurality of flutes. 
     
     
       5. A mechanical broadhead arrowhead comprising:
 (a) an elongated, generally cylindrical body defining a longitudinal axis, the body having a forward end with a sharpened tip, a rearward end having a means for attachment to a shaft of an arrow, and a plurality of recessed slots parallel to the longitudinal axis; and 
 (b) a plurality of delayed deployment blades pivotably mounted in the slots, each blade having the general shape of a sans serif capital letter J with a longer knife portion with a centerline and a shorter wing portion with a centerline, the knife portion having a sharpened edge along the side opposed from the wing portion, the wing portion having a sharpened edge along the side facing the knife portion, each blade having a pivot point where the centerline of the knife portion meets the centerline of the wing portion, each blade adapted to rest in a first position with its knife portion in a slot of the body and its wing portion extending outwardly and forward of the pivot point during flight and each blade adapted to move to a second position with its wing portion in a slot of the body and its knife portion extending outwardly after deployment upon contact with a solid target. 
 
     
     
       6. The arrowhead of  claim 5  wherein the centerline of the knife portion and the centerline of the wing portion form an angle of about 45 to 75 degrees. 
     
     
       7. The arrowhead of  claim 5  wherein the number of recessed slots is two to four. 
     
     
       8. The arrowhead of  claim 5  wherein the body contains a plurality of flutes.
